Dehumidifying device for dew point temperature adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dehumidifying devices struggle to stably maintain a dew point temperature of −20° C. or lower, which is crucial for manufacturing precision instruments and parts sensitive to hygroscopic moisture, as they primarily focus on humidity reduction rather than precise dew point control.
Innovation Solution
A dehumidifying device that adjusts dew point temperature by controlling the rotational frequency of the supply fan, rotating speed of the dehumidifying rotor, opening degree of the blow-out air volume adjustment damper, rotational frequency of the exhaust fan, and opening degree of the exhaust air volume adjustment damper, allowing for precise dehumidification intensity and dew point temperature adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a conventional dehumidifying device is used to reduce humidity in the air, then the humidity level decreases, but the dew point temperature cannot be stably maintained at −20° C. or lower
Solution Approach 1:
The patent implements dynamic control of the dehumidifying device by adjusting the rotational frequency of the supply fan and exhaust fan, and the opening degree of dampers based on real-time dew point temperature feedback. This dynamic adjustment allows the system to adapt to changing conditions and maintain stable dew point temperature at −20° C. or lower, resolving the reliability issue of conventional static dehumidifying systems.
Solution Approach 2:
The patent changes operational parameters (fan rotational frequencies, damper opening degrees) to optimize dehumidification performance. By adjusting these parameters in response to dew point temperature measurements, the system achieves both low humidity levels and stable dew point temperature maintenance, overcoming the limitation of conventional devices that cannot stably maintain −20° C. or lower.
2Reliability
If multiple operational parameters are adjusted to achieve precise dew point temperature control, then dew point temperature stability improves, but device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it receives dew point temperature signals, determines appropriate operational parameters, controls fan rotational frequencies, and adjusts damper opening degrees. By consolidating these control functions into a single multi-functional unit, the patent manages device complexity while achieving precise dew point temperature stability through multiple parameter adjustments.
3Manufacturing precision
If the rotational frequency of fans and opening degree of dampers are adjusted for precise dew point control, then manufacturing precision improves, but energy consumption increases
Solution Approach 1:
The patent optimizes energy consumption by dynamically adjusting operational parameters based on actual dew point temperature conditions. Rather than maintaining maximum fan speeds and fixed damper positions, the system adjusts rotational frequencies and opening degrees to match the required dew point temperature, achieving precise manufacturing control while minimizing unnecessary energy consumption.
